We also express no opinion as to (i) the enforceability of the provisions of the Indentures, Debt Securities, Guarantees, Warrants or Units to the extent that such provisions constitute a waiver of illegality as a defense to performance of contract obligations or any other defense to performance which cannot, as a matter of law, be effectively waived or (ii) whether a state court outside the State of New York or a Federal court of the United States would give effect to the choice of New York law provided for therein.

Courts in the United States have not customarily rendered judgments for money damages denominated in any currency other than United States dollars.

We express no opinion as to whether a Federal court of the United States would render a judgment other than in United States dollars.

We are admitted to practice only in the State of New York, and we express no opinion as to matters governed by any laws other than the laws of the State of New York, the Delaware General Corporation Law and the Federal laws of the United States of America. In particular, we do not purport to pass on any matter governed by the laws of England and Wales, Luxembourg or Bermuda. Insofar as the opinions expressed herein relate to or depend upon matters governed by the laws of other jurisdictions as they relate to Genpact UK, Genpact Luxembourg or Genpact Limited, we have relied upon and assumed the correctness of, without independent investigation, the opinions of Appleby (Bermuda) Limited, Bermuda counsel to Genpact Limited, Allen Overy Shearman Sterling SCS, société en commandite simple (inscrite au barreau de Luxembourg), Luxembourg counsel to Genpact Luxembourg, and Slaughter and May, English counsel to Genpact UK.

We understand that we may be referred to as counsel who has passed upon the validity of the Securities of the Companies in the prospectus and in a supplement to the prospectus forming a part of the Registration Statement, and we hereby consent to such use of our name in said Registration Statement and to the use of this opinion for filing with said Registration Statement as Exhibit 5.1 thereto. In giving this consent, we do not hereby admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission promulgated thereunder.
